dream material, for which an appropriate wish-fulfilment is sought, in a way similar (see above) to the search for connecting ideas between two dream stimuli. To this extent it is true for a number of dreams that the somatic determines what their content is to be. In this extreme case a wish which is not exactly actual is aroused for the purpose of dream formation. But the dream can do nothing but represent a wish in a situation as fulfilled; it is, as it were, confronted by the task of seeking what wish may be represented and fulfilled by means of the situation which is now actual. Even if this actual material is of a painful or disagreeable character, still it is not useless for the purposes of dream formation. The psychic life has control even over wishes the fulfilment of which brings forth pleasure—a statement which seems contradictory, but which becomes intelligible if one takes into account the presence of two psychic instances and the censor existing between them.
There are in the psychic life, as we have heard, repressed wishes which belong to the first system, and to whose fulfilment the second system is opposed. There are wishes of this kind—and we do not mean this in an historic sense, that there have been such wishes and that these have then been destroyed—but the theory of repression, which is essential to the study of psychoneurosis, asserts that such repressed wishes still exist, contemporaneously with an inhibition weighing them down. Language has hit upon the truth when it speaks of the "suppression" of such impulses. The psychic contrivance for bringing such wishes to realisation remains preserved and in a condition to be used. But if it happens that such a suppressed wish is fulfilled, the vanquished inhibition of the second system (which is capable of becoming conscious) is then expressed as a painful feeling. To close this discussion; if sensations of a disagreeable character which originate from somatic sources are presented during sleep, this constellation is taken advantage of by the dream activity to represent the fulfilment—with more or less retention of the censor—of an otherwise suppressed wish.
This condition of affairs makes possible a number of anxiety dreams, while another series of the dream formations which are unfavourable to the wish theory exhibits a different
